IMPROVED GAS-LIGHT MULTIPLIER.'

KNOW ALL MEN BY THESE PRESENTS:

That I, J. F. BOYNTON, of the city of Syracuse, county of Onondaga, andState ofNew York, have ihvented a new and useful Improvement in thatGlass of Apparatus applied to the Increase of the Illuminating Elementsalways necessary in the ordinary illuminating gas for lighting dwellingsand cities,

It is well known that if the ordinary illuminating gas be passed aconsiderable distance through cold tubes or pipes, as is always the casein cold climates, much of the illuminating property is lost; in fact,the hydro carbons, such as benzine, toluole, '&c., which I considervery'important elements, are precipitated in eondensa tion, and may befound at the water-traps of the street mains instead of being carried tothe burners where they are most needed. However perfectly the gas may bemanufactured and started from the works, it will thus be readily seenhow its illuminating properties maybe and are always to agreater or lessdegree diminished before it reaches the consumer. Many methodshave, too,from time to time, been suggested for overcoming the difii culty, andthe most practical are certainly those which will supply the deficientilluminating elements nearest the point of consumption, or where theycannot again be lost. This is the object of my invention, and consists.simply of an apparatus for thoroughly commingling the deficienthydrocarbons with the depreciated gas; and the following is asufficiently accurate account or description to enable any one skilledin such matters to construct the same, when taken in connection with theaccompanying drawings, which orm a part of my specification.

Figure 1 represents a cross-section of the multiplier.

Figure 2, a longitudinal section of the same.

Like letters refer to like parts in zfl'l the drawings.

A A is a box'or receiver, of any cohvenient size and form, for holdingthe carbons and agents for mixing them with the gas. I have preferred tomake mine of cast iron, and about as high as they are wide, and twicethe length of their height. At the top of said box, as shown at an, is aflange projecting inward, which serves, in addition to a broad surface,for receiving the cover as a support for wires or ribs 6 l b b, and towhich are suspended strips or strands of fibrous material, as at c c ca, said strips reaching-down into the liquid in the lower part of thebox, as at L. These wires or ribs are let into recesses or notches inthese flanges to such a depth that when the cover is placed upon the topof the box it prevents the wires from shifting out of place Thehydrocarbons, of which there are great varieties, are poured into themultiplier at O, or any convenient opening in the box, and it isunnecessary to introduce more at any time than to keep the lower ends ofthe fibrous strips well saturated, as it is intended that said stripsshall, by their capillary attraction, lift the carbons toward the top ofthe box, and thereby expose them upon a very extensive surface to thedepreciated gas which'is introduced, as at G, at one end of themultiplier, and after commingling with the exposed carbons passes out atthe opposite end to the burners through the tube H. The immense surfaceand multitudinous points which this fibrous material thus affords in socompact a space will be found, I believe, the very best agentsforcommingling the carbons with the gas.

7 By this arrangement the gas is thoroughly charged with hydrocarbons,whereby its illuminating power is brought up to the highest point. Theconstruction of the apparatus is such as to secure perfect safety andefiiciency, From the manner in which the carburetting-chamber or box isclosed there can be no leak either of liquid or gas, even under stronginternal pressure, which has not been obtained with water or mercuryseals, as

heretofore used. The interior of the box or carburetter I have describedas filledfor partially filled, with capillary material. This I regard asthe best arrangement; but it is evident that the. interior of the closedbox may be divided up so as to form tortuous passages.

The essential feature of my apparatus is a closed box or vessel, withits interior filled, or partially filled, with .ca-pillary material, orits equivalent, so as to secure a large evaporating surface. I do notconfine myself to any form ofbox, or to any kind of packing to closethejoint between the box and its lid or cover, nor to the arrangement ofthe interior of the box for the purpose of securing a large evaporatingsurface, for these may "be all greatly varied without departing from theprinciple of my invention,

l Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, isl 1. A closed box, containingcapillary material, or its equivalents, with entrance and exit-tubes, soas to 4 charge gas with volatile hydrocarbons, substantially asdescribed. 7

2. A box with alid and close joints, so as to form acarburetting-chamber for gas, substantially as described. l 3. A closechamber or box, with cloth or other capillary material on rolls 01supports, substantially as described.
